Technical details
The vulnerability exists in Post Excerpt, Post Custom Field, and Rich-Text Paragraph fields which allow raw HTML via allow_html(), and entity-encoded payloads stored in data-dialog-confirm attributes bypass wp_kses_post() sanitization at save time but are decoded and executed by the browser when the plugin's admin JavaScript passes the attribute value to insertAdjacentHTML(). This is a stored XSS requiring no user interaction, affecting all versions up to and including 3.1.1.
